Customer Q & A

Q1: I'm allergic to smoke, will it protect my lungs from it?
A: Somewhat. HEPA filter media isn't specifically designed for the contaminants that are contained in smoke. While they will certainly filter out some of the molecules found in tobaco, wood fire smoke and exhaust, for better filtration of those specific compounds, you would likely want to use either the optional organic vapor or multigas cartridges. The HEPA filters come standard, so you can try with those and see how well they perform then opt for the cartridges if you find the concentrations of smoke are high enough that they are passing through the HEPA filter. Hope that helps!

Q2: How am I supposed to measure for a mask if I don't have it??? 4.75 or 5.00 Woman of average head size...

A: The measurement is to give you something to compare the distance from the middle of your nose to just under your chin. In general though, the 6291 medium fits most people fine. Generally speaking, if you're less than 6' tall and 240 lbs. or so, the medium will fit with no issues.

Q3: Hi I have asthma and cannot be outside with the weed or grass pollen. I haven't been able to use my outdoor hot tub because of my allergies. I am also disabled an desperate to get back in my hot tub as I helps me greatly. Would I be able to use this product when I'm in my hot tub? If not could you recommend something that I can use? Thanks!

A: You could use any of the masks in the hot tub, just try to avoid getting them wet. With this mask in particular, the body/shell of the mask can be wet but you'll want to keep the filters dry. Additionally, should a little water splash up on them not like you completely submerge the mask, simply allow it to completely air dry and you should be just fine using that set of filters again. Hope that helps!

3M 6291 HEPA Mask

The 3M 6291 HEPA Mask is one my favorite face masks. Unlike disposable masks, the 6291 is durable and can be used repeatedly. I have owned this mask for a several years, and have changed the HEPA filter cartridges twice. I use this mask for just about everything from yard work to more heavy duty projects like like replacing the grout in our shower. Depending on usage, you may have to replace the filters more often, so this will vary depending on use. After several years of service, this my assessment of the 6291 respirator.

What I like about the 3M 6291 HEPA Mask
  • Offers HEPA quality filtration of oil and non-oil based particles
  • Versatile filtration ideal for a wide range of uses from pollen and mold particles while raking leaves to filtering oil based particles you might encounter while staining or working with wood or fiberglass while renovating or working on your home
  • Creates a very tight seal
  • It is durable and easy to clean after dirty projects - rinse respirator itself with warm water or with a mild detergent (filters NOT washable)
  • Fits very snugly with two straps and is fully adjustable
What I did not like about the 3M 6291 HEPA Mask
  • As with any tight sealing mask, in warm conditions it will make the area around my mouth sweat, so some moisture will get trapped inside

In all, the 3M 6291 HEPA Mask is the best masks we offer. With NIOSH P100 filtration, this respirator is one of the most versatile available today. It is completely sealed, non latex, HEPA grade, and you can replace the filters when necessary. If you, have allergies, do a lot of yard work, work in a shop or in places where things toxic and non-toxic particles are a concern, I strongly suggest using this mask. The filtration this mask provides also exceeds the CDC's recommended filtration level (N95) to help prevent the spread of the influenza virus. Aside from it being a little warm with extended use or in warm conditions, there is very little not to like about this durable HEPA respirator.
